Silk-screen printing device

Abstract

Provided is a screen printing apparatus. In the forming of the protrude electrode using the screen printing method, resulting the adhesive force of the solder paste which is transferred by many opening-part groups and the metal mask, the departing of the printing board starts from the perimeter part, finally the middle part of the metal mask departs from the printing board, the occurring of this phenomenon is the main reason for the defective printing which concludes the thickness error of the printing film ,the printing deficiency and so on. Using the different thickness of the mentioned mask component sheet, or the different material, or the different elastic coefficient, connect every mask component sheet which is set on the accessory pattern of the printing baseboard or at all the patterns formed in the scheduled area, and the adjusting equipment which accords to the mentioned connection status and can reproduce random curve is also provided.

Description

technical field

[0001] The present invention relates to a screen printing device, and more particularly to a screen printing device using a printing metal mask whose elastic state can be changed in multiple stages according to the position of the mask. Background technique

[0002] Patent Document 3 discloses a printing method of a conventional screen printing device, and Patent Document 1 or Patent Document 2 discloses a mask to be used. In particular, as a mask used in printing, a thin plate material made of stainless steel is used, a method of processing a pattern opening part by an etching method or a laser method, or a wiring pattern is formed on a conductive metal surface with a resist film, using A metal mask including a pattern opening portion is formed by an additive method of electroplating, and such a metal mask is used. In addition, Patent Document 1 discloses that, on a conductive substrate on which a photosensitive resin layer is laminated, by directly irradia...
